Английский язык на слух. Тренажер is a free Android app developed by Sergei Lupov, categorized under Education & Reference. The app helps users improve their English listening and comprehension skills. The app works offline and plays phrases with subject pronouns and verbs in random order in the present, past, and future tenses, in affirmative, negative, and interrogative forms. After a pause, the app automatically pronounces the phrase's translation for self-checking.

The app has several features that make it easy to use. Users can choose specific phrases or sections to practice and can run the trainer by pressing the "Start" button. The app's settings allow users to select pause timeseconds) and one of three modes:

• The text is pronounced in English, then (after a pause) in Russian;
• The text is pronounced in Russian, then (after a pause) in English;
• The text is pronounced only in English (with a pause between phrases).

It is recommended to alternate between English-Russian and Russian-English modes. In the second mode, it is better to pronounce English phrases out loud.
